Plumbing Pipe Market (Major 25 Pipe Types) in Japan: Research Findings in 2025
Based on Shipment Volume of 25 Types, the Plumbing Pipe Market Decreased by 4.1% Year over Year to 2.117 Million Metric Tons, When Converted into Steel Pipe Weight
Yano Research Institute (the President, Takashi Mizukoshi) conducted a survey of the major 25 types of plumbing pipes in Japan and found out the trends by pipe and by segment, trends of market players, and future perspectives.
Market Overview
Based on the shipment volume of the 25 major types of plumbing pipes that are converted into steel pipe weight, the estimated market size for plumbing pipes shrank by 4.1% year over year, reaching 2.117 million metric tons in FY2024. Despite demand from construction sites for urban redevelopment projects, which are one of the major destinations for plumbing pipes, soaring construction costs and labor shortages are causing projects to be reevaluated, and delayed. This results in slower demand for plumbing pipes and market shrinkage.
Noteworthy Topics
Environmental Initiatives in the Plumbing Pipe Market
Efforts have been made to promote the circular economy in the plumbing pipe market. These efforts include launching products that reduce greenhouse gas emissions and establishing a system for collecting and reusing waste materials.
In the case of carbon steel pipes for standard piping, construction facilities and plants have started to adopt products that use green steel, which significantly reduces CO2 emissions during the manufacturing process. Polybutene pipes can be recycled due to their thermoplastic properties, which allow the pipes to soften for molding when heated and stiffen when cooled. There have been cases of waste polybutene pipes generated at new housing or maintenance sites being collected, regenerated into pellets and returned as raw materials.
Future Outlook
Based on the shipment volume of the 25 major types of plumbing pipes that are converted into steel pipe weight, the plumbing pipe market is forecast to shrink by 0.8% year over year, reaching 2.101 million metric tons in FY2024.
There is potential demand, as urban redevelopment projects in the Kanto region are steadily progressing, and the Kansai region is facing redevelopment projects for integrated resort businesses, as well as Superconducting Maglev and existing Shinkansen projects.
However, labor shortages in construction sites are forcing construction companies to prioritize order acceptance. This creates uncertainty regarding potential demand. Consequently, the market is trending downward.
In the housing sector, demand for plumbing pipes is expected to decline in the long term. Therefore, plumbing pipes that depend heavily on the housing sector will likely decline as well.
Conversely, demand from the civil engineering sector is promising. Currently, attention is being drawn to aging and safety measures for the basement infrastructure, including sewage lines. The government's “National Resilience Policy,” effective in FY2026, addresses this issue. This will likely increase demand for plumbing pipes used in civil engineering projects.

What are the Major 25 Types in the Plumbing Pipe Market?
This research focuses on the 25 types of plumbing pipes, which were selected from various applications, including pipes installed in buildings for piping arrangements and in infrastructure such as waterworks, gas lines, electrical systems, and other civil engineering works. Market size is calculated based on the total shipment volume for each application at manufacturers, which were converted into steel pipe weight values.
These values are calculated by measuring the specific gravity of each of the 25 materials against that of a steel pipe, which is assumed to be 1.
